Melaleuca scalena is a plant in the myrtle family, Myrtaceae and is endemic to the south west of Western Australia. Plants of this species were previously included in Melaleuca uncinata or broombush until a review of that species in 2004. Its leaves are narrow cylinders, the flowers in small yellow heads and the fruits tightly packed together in oval clusters. This species is very similar to Melaleuca hamata but the plants have a comparatively scruffy or less strong and healthy appearance.

Taxonomy and naming
Melaleuca scalena was first formally described in 2004 by Lyndley Craven and Brendan Lepschi in Australian Systematic Botany from a specimen collected Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). north-west of Babakin.[2][3] The specific epithet (scalena) is from the Latin word meaning "unequal" referring to the impoverished appearance of this species compared to Melaleuca hamata.[1]
Distribution and habitat
Melaleuca scalena occurs in and between the Wyalkatchem, Mount Walker, Woodanilling and Dumbleyung districts[1] in the Avon Wheatbelt, Coolgardie, Esperance Plains, Jarrah Forest, Mallee and Yalgoo biogeographic regions. It grows in gravel, sand or loam on flats and drainage lines near salt lakes.[4]
Conservation
Melaleuca scalena is listed as "not threatened" by the Western Australian government Department of Parks and Wildlife.[4]
